WRAPPING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 632,983, dated September 12, 1899.

Application filed can. s, 1898.

To all whom it may concern:

Be it known that I, JOSEPH ALEXANDRE LOUIS BARBIER-DUROZIER, a citizen of the Republic of France, and a resident of St. Marcellin, (Isere,) France, have invented certain new and useful Improvements in Machines for Wrapping Up Circulars, Books, 850., of which the following is a specification. This invention relates'to amachine for wrapping up newspapers, books, circulars, and the like. The improved machine is represented, by way of example, in the accompanying drawings, in which Figure 1 is a vertical longitudinal section taken upon the line 1 1 of Fig. 3. Fig. 2 is a vertical cross-section taken upon the line 2 2 of Fig. 3. Fig. 3 is a plan view as seen from above. Fig. 4 is a detail view of one of the parts of the machine. Figs. 5, 6, 7, and 8 are detail views intended to explain the method of operation.

Upon a plate a is arranged a pile of wrappers 00, of suitable size for the printed matter which they are intended to surround individually. This plate is mounted upon the upper portion of a screw-threaded rod a entering a nut a which is supported by a crosspiece a of the flange Bof the machine. The said nut, which is free to rotate upon itself but not to become displaced vertically, comprises at its periphery a toothed crown b, which gears with an endless screw b, to which motion is imparted from the main shaft by means of helicoidal gear-wheels b and 6 or in any other suitable manner. Owing to this the plate a is constantly raised, and this vertical movement is regulated according to the thickness of the wrappers and also according to the rapidity of the operations to which the said wrappers are submitted.

Above the plate a and toward its extremities are provided two boxes 0 and O, filled with an adhesive substance, the oblique bottom 0 of which, in the form of a register capable of regulation, Fig. 4., allows a certain quantity of such adhesive substance to pass or ooze through. Normally these boxes bear lightly upon the pile of wrappers m, and the adhesive substance which they allow to pass causes the upper wrapper on the heap to adhere thereto in such a manner that when they Serial No. 693,895. (No model.)

are subsequently raised they carry with them the said top wrapper and separate it from the remainder of the pile. Each of the boxes 0 O is suspended from a rod d or d passed through a cross-piece e or e, Which is rigidly connected with a frame formed of two rods ff or f f and two cross-pieces g h or g h.

The rods f f and f f pass through the sockets f which serve as guides for them. The cross-pieces g g are attached to the crossp'ieces e e, respectively, by means of a sleeve which enables the interval between the boxes 0 O to be regulated as desired, and each of the lower cross-pieces h h comprises a roller engaging in the fork of a lever D, pivoted at i and provided with a roller j, in contact with a cam E or E, Figs. 1, 2, and 7, rigidly fixed upon the principal shaft A. Under the influence of the cams E E the two boxes Cand C are raised simultaneously and carry with them, Fig. 5, the paper wrapper m, which adheres thereto as above stated. It should be noticed that the boxes 0 O in redescending in the manner hereinafter explained rest upon the heap of wrappers, while compressing to a greater or less extent spiral springs passed upon the rods d cl", which have free play in the respective cross-pieces e e. The spiral spriu gs serve as regulators.

Upon one side of the plate a is arranged a tablet F, comprising a horizontal, portion and an inclined portion, which latter is adjusted in obliquely-arranged slides 7t 70. This tablet is supported bythe levers G G, which are rigidly connected with an axis Z, provided with an arm Z, furnished with a roller Z resting upon a cam H, Figs. 1 and 8, rigidly fixed upon the main shaft A. Under the influence of this cam H and of the inclination of the slides 7c the tablet F passes from its position of repose, Fig. 2, to its operative position, Figs. 7 and 8that is to say, it enters between the heap of wrappers w and the wrapper on, raised by the lifterboxes 0 O. In this position it serves as a support for the lifted wrapper m, and thus enables the package y, which it is desired to surround with a wrapper to be placed upon this latter. It should be noticed that the upward displacement of the boxes 0 O is such that the lifted wrapper x extends slightly beyond the level of the tablet F and that it will fall under the weight of the printed matter 1 which has been placed in position.

The extremities of the wrapper which adhere to the boxes C 0 remain raisedthat is to say, in a suitable position for being finally turned down upon the printed matter which the wrapper is to surround. Eehind the boxes 0 C are arranged rollers I I, intended to approach each other toward the center of the machine, the effect of these rollers being to produce the turning down in question. Each of these rollers is passed upon an axis supported by rods 'm m or m m, capable of sliding in sockets n n or n n, which are adapted to oscillate upon supports 0 0 or 0 0. The axis of each of the rollers I I is in addition attached by a connection 1) to the upper extremity of a lever J or J, pivoted at q or q and provided with a roller 5, which is in contact with a cam K or K, rigidly fixed upon the main shaft A. Under the influence of the cams K K the rollers I 1 advance toward the center of the machine while remaining free to oscillate around the pivot of the sockets n n and n n. This oscillation is necessary by reason of the various thicknesses of the packets of printed matter which may be required to be wrapped up. The cams K K are attached in such a manner that the roller I advances first and the roller 1 advances only at the moment at which the roller I retires. The roller 1 in its advance detaches from the box (3, the projecting extremity of the wrapper which is adherin g thereto turns it down upon the packet, Fig. 6, and sticks it slightly upon the same, owing to the point or strip of adhesive substance which it carries with it. The roller I produces the same eifect upon the extremity of the wrapper which is adhering to the box C, with this difference that it sticks this extremity upon that previously turned down. The pressure of the turning down and sticking rollers I and I is exerted upon the tablet F, which serves as a support both for the wrapper and the packet. In their travel toward the center of the machine the rollers I I act, respectively, upon fingers or clips i [and t 25, which they press down upon the packet Y for the purpose of retaining it in position, while the extremities of the wrapper as are being turned down and stuck. .The fingers in question are arranged upon each side of the lifting-boxes C O, and under the action of small springs tending to turn them down constantly toward the center of the machine that is to say, upon the packeteach of the fingers is provided with a tail, with which the axis of the corresponding roller I I engages, of which axis they follow the movement. .Vhen these rollers advance toward the center of the machine, the fingers being acted upon by their springs are applied upon the packet and maintain it upon each side of the wrapper. "When upon the other hand these rollers recede from the center, they act upon the said tails and the fingers are raised. In any event it follows from the foregoing that the packet is perfectly wrapped. up and that -M in a fixed position.

the wrapper is at the same time stuck and adheres to the packet in such a manner as not again to become detached. It is then necessary to remove the packet so made up in, order to enable the operation above described to be repeated. It is at this moment that the cam H allows the tablet F byits own weight to again resume its initial position. In this movement the tablet F carries withit the wrapped-up packet, and the boxes C C under the influence of their respective cams E E, are depressed in the direction of the pile of wrappers 00, so as to remove the top wrapper, as above described. One of the extremities of the made-11p packet conveyed upon the tablet F comes intocontact with the feedroller I, which rotating in the direction of the arrow, Fig. 7, feeds the packet Y over onto the ,inclined plane L, which conducts it toward a receptacle M, provided for the reception of the made-up packets. The roller L is caused to rotate by means of a small end-,

less cord a, passing over the grooved pulleys o and '0, arranged upon the main shaft A and the axis of the said roller L, respectively.

The receptacle for the made-up packets consists of a prismatic box M, which is rigidly fixed upon a pivot p upon which is attached the internal extremity of a spiral spring R, the outer extremity of which is attached to a fixed barrel p mounted upon a suitable support. Tension is produced in the spring R in the ordinary manner by acting upon the square portion of the pivot 19 To the box M is rigidly fixed a crown g which fits upon the barrel p and the exterior of which is provided with two projections 3 3 arranged diametrically opposite one to the other. One of the projections strikes against a finger g and serves to maintain the box or receptacle The finger g forms one with a slide Q, provided with a stud t which is applied under the influence of a spring against the edge of a disk 1 provided with a notch and keyed to the lower extremity of a vertical shaft V, which is driven in a predetermined ratio by the main shaft A by means of transmission-gear b b d d e 2 The ratio of these parts is such that the shaft V completes one revolution for each twentyfive revolutions, for example, of the main shaft A. It results from this that upon each twenty-fifth revolution of this shaft the notch t" of the disk 25 is presented to the finger g which engages therein, thus releasing the projection s of the crown g or the box M, which under these conditions and under the influence of the spring R turns upon itself to be again locked by the finger g This box after having eifected a half-revolution upon itself continues to receive the made-up packets and then again effects a half-revolution, and so on in succession. It follows from this that the packets are piled one upon the other in heaps of twenty-five, and that the pile formed by them is absolutely regular. It should be understood that the figure twenty-five is taken by way of example only and that the box may be caused to oscillate when twenty, thirty, forty, or any other desired number of packets have been made up. The disengagement of the finger (1 may be utilized for actuating a device registering the number of packets made up. When the box M is filled to the desired extent, the packets are withdrawn, and to effect this it is only necessary to turn down one of its sides, which is hinged and provided with a catch with this object.

Such is the construction and operation as a whole and in its details of the machine for wrapping up circulars or the like which I have devised and which it will of course be understood may be constructed in all dimensions and without any exact limitation as to the arrangement of details and accessories or with respect to any of the methods of transmission, which have been described with the sole object of rendering the fundamental principle of the said machine comprehensible. It should finally be stated that the frame B of the machine somewhat closely resembles that of a sewing-machine; that upon this frame is arranged a table-top T, in which are formed suitable apertures for the movements of the parts and of the wrappers and circulars or the like, and that the mainshaft A is provided with fast and loose pulleys P and P for the purpose of driving from the motor and with a hand-wheel O for starting and regulating the machine.

I claim as my invention 1. In a machine for wrapping up circulars or other printed matter, the combination with a plate for the piled-up wrappers and means for imparting a uniform ascending movement thereto, of boxes filled with adhesive substance and adapted to allow the same to ooze out at their lower portions, said boxes adapted to be applied to the pile of wrappers and lift the top wrapper therefrom, a tablet adapted to slide beneath the lifted wrapper to serve as a support for the said wrapper and for the circular to be wrapped up, and rollers adapted to move in succession in the direction of the said supporting-tablet, as and for the purpose described.

2. A machine for wrapping up circulars, &c., having rollers for turning down the ends of the wrapper,'a plate a to support a pile of wrappers, boxes 0 0 containing an adhesive substance, frames carrying said boxes and adapted to move vertically to the plate CL, and adapted to lift the topmost wrapper of the pile and hold its ends in a curved position to permit the roller to act upon it, as and for the purpose set forth.

3. A machine for wrapping circulars, 850., having rods, pivoted sockets, in which said rods can slide, and turning-down rollers I I mounted on the rods, with actuating-levers for the latter and means to cause said rollers to, alternate in their movements, substantially as described.

4. A machine for Wrapping up circulars, 850., having a tablet and oblique slides there for, in combination with means for lifting one wrapper of a pile, a suitable mechanism for raising said tabletand interposing it between the pile of wrappers and the lifted wrapper, substantially as described.

5. In a machine for wrapping circulars, &c., the combination of the turning-down levers I and I with spring clips or fingers unat tached to but operated by said levers and adapted to bear on the packet while the extremities of the wrapper are being turned down, substantially as described.

6. A machine for wrapping up circulars, &c., having a tablet F, inclined sides upon which it is mounted, a cam H upon the shaft A to actuate said tablet, in combination with a roller L, an inclined plane L and a stackin g-box M, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
